THREAD-PLACER.

Application filed August 18, 1916.

To all whom it may concern:

Be it known that I, ALFRED I MORELL, a

In this type of looms, after the operation of the transfer mechanism, aportion of weft extends from the selvage toward the shuttle box, and itis necessary that this portion of weft should. be immediately severedand removed before it can be woven into the cloth. F or this purpose, atemple thread cutter is used and it is the object of my presentinvention to provide a device which shall cooperate with this threadcutter to insure the positive cutting of this outgoing weft. Q

With this object in view, one feature of my invention consists in theprovision of a thread placer carried by the lay and adapted to beadvanced relatively to the reed after the weft transfer, such movementpositively presenting the outgoing weft to the action of the templethread cutter. In the preferred form of my invention the thread placeris actuated indirectly from the transferrer arm, said arm beingetfectiveto move an actuator to operative position. Provision is also made forwithdrawing said actuator after the operation of the thread placer. ihislatter mechanism is herein shown as under the control of the feelermechanism and as adapted to withdraw the actuator after the secon'doperation of the thread placer. 1 also provide for the retraction of thethread placer as the shuttle and lay reach their extreme forwardposition, thereby avoiding engagement with the temple or temple threadcutter. I

My invention further relates to certain arrangements and combinations ofparts which will be hereinafter described and more particularly pointedout in the appended claims.

A preferred form of my invention is shown in the drawings in whichFigure 1 is a side elevation of my im- Specification of Letters Patent.

Serial No. 115,609.

proved thread placer and the operating mechanism therefor, certain partsof the loom being shown in section;

Fig. 2 is a top plan view of parts of the mechanism shown in Fig. 1,taken along the line '2-2 in said figure;

Fig. 3 is a top plan view of additional. mechanism shown in Fig. 1,taken along the line 3+3 in that figure;

Fig. 4: is a detail sectional View taken along the line 1 l in Fig. 3,and

Fig. 5 is a longitudinal sectional view of the spring plunger whichpositions the actuator.

Referring to the drawings, 1 have shown a temple of the usual formmounted upon the breast-beam 11 and provided with a movable threadcutting element 12. The lay is indicated at 13 supported upon the usualsword 1 1 and provided with the usual reed 15 and hand rail 16. Theshuttle 17 is indicated in its position on the lay.

The thread placer comprises an arm 20 secured to a shaft 21 in positionto swing between two adjacent dents of the reed 15. The shaft 21 ismounted in bearings 22 and 23 formed on a bracket 2 1 secured to thesword 1 1. A coil spring 25 is fixed at one end to the bearing 22 and atthe opposite end the shaft may be adjusted. Stops 27 and 28 cooperate tolimit the backward movement of the thread placer 20. V A cam arm 30 isfixed to the opposite end of the shaft 21, and supports a double-facedcam 31 through which the thread placer is actuated.

I will now described the mechanism for moving the cam 31 and actuatingthe thread placer. A portion of a stationary weft magazine 35 is shownin the drawings, said magazine being provided with a rock shaft 36mounted in fixed bearings on the magazine and connected to mechanism notshown from which the rock shaft receives motion on any alternate beat ofthe lay if the-feeler mechanism calls for a change in filling. Forfurther illustration and a more complete description of thismagazinemechanism reference is made to the patent to Ryon, No. 1,030,748 issuedJune 25, 1912, the shaft 36 of this application corresponding to theshaft 36 of the patent.

An actuator 40 is mounted upon a fixed Patented Mar. 19, 1918. I

pivot ll carried by themagazine 35, and is provided with an extension42" having notches i3 and 4% adapted to cooperatewith.

a spring plunger 45 by which means the actuator may be retained ineither operative or inoperative position. The details of the springplunger are clearly shown in Fig. 5,

the plunger being mounted in a fixed sleeve 46 carried by the magazine.

A stud 47 is carried by the actuator 40 and is movable with the actuatorinto the path of travel of the cam 31. For moving the actuator from itsnormal inoperative position to its operative position I provide a lug 50upon the outer face of the 7 regular transferrer arm 51. As this transferrer arm moves downward to eject a substantially exhausted weftcarrier, the.

. actuator is also moved downward until the stud 47 occupies theposition shown in dotted lines in Fig. 1, in which position it isretained by the spring plunger 45.

As the lay continues its forward movement, the stud 47 engages the cam31 and swings the thread placer forward to carry the outgoing weft intothe path of the temple thread cutter 12. As the lay continues to moveforward, the cam 31 passes beyond the stud 47 and the thread placer isretracted by the spring before it engages the temple 10 or its'threadcutter 12.

This operation of the thread placer is once repeated after which theactuator 40 is removed to its inoperative position. The devices for thusremoving the actuator comprise a rod 52 threaded into a head 53 pivotedat 54: to a member 55, said member being loosely mounted on the shaft 36and'be- 'ing actuated by a rod 56 preferably formed integral with theusual rocker 58 carried by the shaft 36. The rod 56 is freely slidablelongitudinally through an opening in themember. 55. The threaded rod 52at its lower end is offset to form a shoulder and engages a lug 60 uponthe back side of the actuator A0.

The rock shaft 36 and the rocker 58 re-v ceive movement before theoperation'of the transferrer arm 51, and the rod 52 is thus lowered topermit movement of the actuator A0 by the transferrer arm. The actuatorre mains in operative position until the shaft 36 and rocker 58are'restored to their inoperative positions, at which time the actuator40 is also restored to its inoperative osition. I have thus provided athread placer which is positively actuated by the transferrer mechanismand which is controlled 0091:: of this patent may be obtained for in itsactuation by the weft detecting mechanism of the loom. The placer isarranged; to present thethread positively to the temple thread cutterwhile at the same time it is itself withdrawn beforeengagementtherewithcan occur.

Having thus described my invention it will be evident that other changesand modifications can be made therein by those skilled in the artwithout departing from the spirit and scope thereof as set forth in theclaims, and I do not'wish to be otherwise limited to the details hereindisclosed.

What I claim is 1. In aloom, a lay havinga reed, a temple threadcutter,'a-thread placer movable 3. In a loom, a lay having a reed, athread placer mounted on the'lay and movable relatively to said reed, atransferrer arm, and connections between said placer and saidtransferrer arm whereby said transferrer arm controls the actuation ofsaid placer.

4. In a loom, a lay, a' thread placer mounted thereon, a cam movabletherewith, an actuator effective through said cam to give said placer anoperative movement, means to move. said actuator to operative positionrelativelyto said cam,'means to thereafter return said actuator toinoperative position, and a spring effective to move said cam and placer1n the reverse d1- rectlon, saldcam permitting such reverse movement ofsaid placer during the continned forward movement of the lay.

5.111 a loom, a thread placer,- an arm secured thereto having adouble-faced cam thereon, a cam stud to actuate said cam, an

arm supporting said stud, a spring plunger.

to hold said arm in a selected position, and feeler-controlled mechanismfor moving said arm to operative and inoperative p0 sitions.

In testimony, whereof I have hereunto affixed my signature; r A
